Lib Dem leader Nick Clegg said he "acted immediately" when he was told legal proceedings were being taken against MP Mike Hancock, who has been accused of sexual misconduct.
The Deputy Prime Minister said: "You can only react to things that are put to you and the first time that specific allegations were put to me was when legal proceedings were launched at the beginning of last year.
"That is when I acted, I acted immediately because I was as appalled as anyone by the seriousness of these allegations, and that's why I now want to see justice done.
"The process, which is now in the courts, should be seen through to its conclusion".
